<h2>SQLite Release 3.7.9 On 2011 November 1 (3.7.9)</h2><p><ul>
<li>If a search token (on the right-hand side of the MATCH operator) in
    <a href="../fts3.html#fts4">FTS4</a> begins with "&#94;" then that token must be the first in its field
    of the document.  <b>** Potentially Incompatible Change **</b>
<li>Added options <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachehit">SQLITE_DBSTATUS_CACHE_HIT</a> and <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachemiss">SQLITE_DBSTATUS_CACHE_MISS</a>
    to the <a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface.
<li>Removed support for <a href="../compile.html#enable_stat2">SQLITE_ENABLE_STAT2</a>, replacing it with the much
    more capable <a href="../compile.html#enable_stat3">SQLITE_ENABLE_STAT3</a> option.
<li>Enhancements to the sqlite3_analyzer utility program, including the
    --pageinfo and --stats options and support for multiplexed databases.
<li>Enhance the <a href="../c3ref/data_count.html">sqlite3_data_count()</a> interface so that it can be used to
    determine if SQLITE_DONE has been seen on the prepared statement.
<li>Added the <a href="../c3ref/c_fcntl_chunk_size.html#sqlitefcntloverwrite">SQLITE_FCNTL_OVERWRITE</a> file-control by which the SQLite core
    indicates to the VFS that the current transaction will overwrite the
    entire database file.
<li>Increase the default <a href="../malloc.html#lookaside">lookaside memory allocator</a> allocation size from
    100 to 128 bytes.
<li>Enhanced the query planner so that it can factor terms in and out of
    OR expressions in the WHERE clause in an effort to find better indices.
<li>Added the <a href="../compile.html#direct_overflow_read">SQLITE_DIRECT_OVERFLOW_READ</a> compile-time option, causing
    <a href="../fileformat2.html#ovflpgs">overflow pages</a> to be read directly from the database file, 
    bypassing the <a href="../c3ref/pcache_methods2.html">page cache</a>.
<li>Remove limits on the magnitude of precision and width value in the
    format specifiers of the <a href="../c3ref/mprintf.html">sqlite3_mprintf()</a> family of string rendering
    routines.
<li>Fix a bug that prevent <a href="../lang_altertable.html">ALTER TABLE ... RENAME</a> from working
    on some virtual tables in a database with a UTF16 encoding.
<li>Fix a bug in ASCII-to-float conversion that causes slow performance and
    incorrect results when converting numbers with ridiculously large exponents.
<li>Fix a bug that causes incorrect results in aggregate queries that use
    multiple aggregate functions whose arguments contain complicated expressions
    that differ only in the case of string literals contained within those
    expressions.
<li>Fix a bug that prevented the <a href="../pragma.html#pragma_page_count">page_count</a> and <a href="../pragma.html#pragma_quick_check">quick_check</a> pragmas from
    working correctly if their names were capitalized.
<li>Fix a bug that caused <a href="../lang_vacuum.html">VACUUM</a> to fail if the <a href="../pragma.html#pragma_count_changes">count_changes pragma</a> was
    engaged.
<li>Fix a bug in <a href="../vtab.html">virtual table</a> implementation that causes a crash if
    an <a href="../fts3.html#fts4">FTS4</a> table is <a href="../lang_droptable.html">dropped</a> inside a transaction and
    a <a href="../lang_savepoint.html">SAVEPOINT</a> occurs afterwards.
<li>SQLITE_SOURCE_ID: 
    "2011-11-01 00:52:41 c7c6050ef060877ebe77b41d959e9df13f8c9b5e"
